Out of idle curiosity, I decided to generate disassembly of both macaddr_cmp_internal(), and the patch's abbreviated comparator. The former consists of 49 x86-64 instructions at -02 on my machine, totaling 135 bytes of object code. The latter consists of only 10 instructions, or 24 bytes of object code. -- Peter Geoghegan -- Sent via pgsql-hackers mailing list (pgsql-hackers@postgresql.org) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-hackers
